Application led December 10, 1906. Serial No. 347,172.

fo all whom it may concern:

Be it known that I, EDWARD M. LANG, Ir., a citizen of the United States,residing at Portland, in the county of Cumberland and State of Maine,have invented an Improvement in Manufactured Solder; and I do herebydeclare that the following is a. full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to the manufacture of solder particularly forthe'purpose of soldering can caps, as well as the tops and bottoms ofcans.

It consists in a ring or washer of solder between the upper and lowersurfaces of which ring or washer is inclosed a fiux'which is distributedwith substantial uniformity throughout the ring. Where, however, it isto be made use of in soldering a cap or top of other than circular form,the ring or washer is made of a shape to conform thereto. The ring orwasher is curved to enable it better to be received into and fit thegroove around the stud in the top of the can. Such ring or washercontaining as it does the necessary amount of fluit to enable thesoldering of each cap to be accomplished, the process of soldering isperformed with greater thoroughness by reason of the substantialuniformity of the distribution of the iluX While the manner in which itis inclosed .between the surfaces of the ring is such as to enable it tobe transported for long distances or kept for any length of time withoutloss of flux either by evaporation or by handling.

I prefer that the ring should be split, as shown in Figures l and 2whereby the ring or washer can be adjusted to the grooves and caps inspite of the variations which are found in them caused either bythewearing away of the dies or from other causes. i ln the drawing: Fig4lis a top plan of the washer; Fig. 2 is a vertical section of the same;Fig. 3 is a vertical section of the end of the can with curved solderring and cap ready to be assembled.

Referring to the drawing, the ring or washer c is shown in Figs. l -2,the flux b being' completely inclosed between the upper and lowersurfaces of the ring c. In Fig. 5, the method of using the ring in solfdering can caps is shown. The ring c is placed in the groove or seat earound the stud of the can d and the cap f placed in the groove of thering or washer c when the soldering process is completed in the usualmanner; Y

What I claim is:

As a new article of manufacture, a split solder ring, curved uniformlyin cross section to fit around the edge of n can cap, :1nd having alayer of flux therein, entirely inclosed by the solder', substantiallyas described.'

In testimony whereof, that I claim the foregoing as my invention I havehereunto set my hand this seventh day of December, A. D. 1906.
